Abstract: A method and system capable of identifying ectopic foci, rotors, or conduction pathways involved in reentrant arrhythmias within cardiac tissue, and then treating identified ectopic foci, rotors, and/or pathways with either lethal or sub-lethal temperatures. The system includes a medical device having one or more mapping elements and one or more treatment elements, and a computer programmable to identify ectopic foci and rotors based at least in part on signals received from the one or more mapping elements at one or more locations.

Abstract: A catheter including a proximal end and a distal end. An expandable element coupled to the distal end is included, the expandable element including a proximal portion and a distal portion, the expandable element defining an exterior surface. A first plurality of electrodes coupled to the exterior surface of the distal portion of the expandable element are included, each of the first plurality of electrodes being selectively operable to transmit unipolar radiofrequency energy. A second plurality of electrodes coupled to the exterior surface of the proximal portion of the expandable element are included, each of the second plurality of electrodes being selectively operable to transmit bipolar radiofrequency energy.

Abstract: A short term usage device is provided for treating urinary incontinence. The device may extend the length of the urethra from internal to the bladder to external to the outside the body. A proximal component, when external to the body, prevents the device from leaving the urethra and entering into the bladder and prevents the device from leaving the urethra and exiting the body. A distal component, when internal to the bladder, prevents the device from leaving the urethra and exiting the body and prevents the device from leaving the urethra and entering into the bladder. The device is configured with a mechanism to regulate urine flow using physiologically created pressures that are applied to the distal portion of the device.

Abstract: An implantable medical device for delivering electrical cardiac therapy includes a first implantable housing containing a battery. There is also a second implantable housing separate from the first implantable housing and containing at least one of: electronic circuitry adapted to evaluate and initiate electrical cardiac therapy, a storage capacitor and an electrode structure comprising a sensing electrode, a pacing electrode and a therapy electrode. There is a method of providing electrical cardiac therapy by implanting a first housing containing a battery into a first implantation site within the body. Then, implant a second housing separate from the first housing into a second implantation site within the body. The second housing contains at least one of: electronic circuitry adapted to evaluate and initiate electrical cardiac therapy; a storage capacitor and an electrode structure comprising a sensing electrode, a pacing electrode and a therapy electrode.

Abstract: The subject invention concerns vascular prosthetic devices and methods for ascending aorta and/or valve replacement in humans and animals. In one embodiment, a device of the invention includes a vessel-like structure having a first end adapted for surgical attachment to a left ventricle, a second end adapted for surgical attachment to an aorta, and, interposed between the first and second ends, a sinus portion configured in the shape of the sinuses of Valsalva in a human aortic valve.
